摘要： A proposal for a DVB-C2 baseline system, mainly focused on the channel coding and bit interleaving modules for spectrally efficient modulation is described. Due to the implementation simplicity of the low density parity check (LDPC) codes standardized in the DVB-S2 specification, it is proposed to extend their application to cable channels and choose the subset with long block length ( L = 64800 ) and medium to high rates ( 2/5 ≤ R ≤ 9/10 ) as the forward error correction (FEC) codes of DVB-C2 systems. Due to the non-uniform bitwise error protection inherent to high-order modulations (e.g. 256-QAM, 1024-QAM) and irregular LDPC codes (e.g. DVB-S2 codes), there exists a mismatch between the modulation and the channel coding in general if the two modules are developed independently but concatenated directly. To match the error resilience of a finite-length channel code and a given constellation, the principles described herein design a bit interleaver and insert it between the channel encoder and the modulator. As a result, a better tradeoff between bandwidth-efficiency and power-efficiency can be achieved with a minor increase of hardware complexity.
摘要翻译：描述了主要关注用于频谱高效调制的信道编码和比特交织模块的DVB-C2基线系统的提议。由于在DVB-S2规范中标准化的低密度奇偶校验（LDPC）码的实现简单性，提出将其应用扩展到有线信道，并选择长块长度（L = 64800）和中到高的子集速率（2/5 = R = 9/10）作为DVB-C2系统的前向纠错（FEC）码。由于高阶调制（例如256-QAM，1024-QAM）和不规则LDPC码（例如DVB-S2代码）固有的不均匀的逐位错误保护，一般在调制和信道编码之间存在不匹配如果两个模块是独立开发的，但是直接连接。为了匹配有限长度信道码和给定星座的错误弹性，本文描述的原理设计了一个比特交织器，并将其插入到信道编码器和调制器之间。因此，可以通过轻微增加硬件复杂性来实现带宽效率和功率效率之间更好的权衡。

摘要： A system/method is shown for reusing digital video broadcasting for satellite, second generation (DVB-S2), low-density parity check (LDPC) codes, and hence also DVB-S2 hardware, in digital video broadcasting for cable, second generation (DVB-C2) contexts. LDPC codes are susceptible to an error threshold, beyond which the coded information cannot be accurately retrieved. By matching the varying levels of protection within an LDPC codeword with the varying levels of protection in quadrature amplitude modulation, the number of errors can be kept below the error threshold.

摘要： The present invention relates to code-dependent bit interleavers for parallel non- uniform channels. Since the channel dependence of a given code ensemble is dominated by the mutual information between the channel input and output, the present invention proposes to simplify the analysis about the decoding behavior by using a set of surrogate binary erasure channels (BEC). The approximation of the actual channel by the surrogate BEC is established on the equivalence of bitwise capacities, which represent the mutual information between the uniformly-distributed binary input and the likelihood ratios of the effective parallel AWGN channels. Moreover, the transition of the erasure probabilities is modeled by a linear difference equation around the decoding threshold SNR, from which we can derive a necessary condition on the convergence of decoding iterations and achieve a useful guideline for the configuration of the bit interleaver.

摘要： Methods, systems, and devices for wireless communications are described. In some systems, a base station may transmit a downlink pre-emption indication (DLPI) or an uplink cancellation indication (ULCI) to a user equipment (UE) to indicate that a subset of resources of a scheduled downlink or uplink data transmission have been pre-empted or canceled. As such, the UE may either empty a buffer at the UE associated with the subset of resources or refrain from transmitting over the subset of resources based on receiving the DLPI or the ULCI, respectively. In some aspects of the present disclosure, the UE and the base station may support one or more inter-UE multiplexing schemes to increase a likelihood for the UE to receive the DLPI or the ULCI or to otherwise avoid collisions with communications between the base station and one or more other UEs.
